Write a program in C to convert decimal number to binary number using the function.

#include <stdio.h>

void dectobin(long int);

void main()

{

    long num;

    printf(“Enter a decimal integer: “);

    scanf(“%ld”, &num);

    dectobin(num);

}

void dectobin(long intdec_num)

{

    int i=0,remainder;

    char bi[1024];

    while (dec_num> 0)

    {

        remainder = dec_num % 2;

        bi[i++]=remainder+’0′;

        dec_num = dec_num / 2;

    }

    printf(“Its binary equivalent is: “);

    for(–i;i>=0;i–)

        printf(“%c”,bi[i]);

}

Output:

Enter a decimal integer: 95

Its binary equivalent is: 1011111
